I'm trying to make a rollback due a deploy failed, my server code is on java, and also i'm using App Engine Eclipse PlugIn for. my appcfg.sh file is located at /Applications/eclipse/plugins/com.google.appengine.eclipse.sdkbundle_1.7.5/appengine-java-sdk-1.7.5/bin/appcfg.sh

but i get "Command not Found" when i try this sudo /Applications/eclipse/plugins/com.google.appengine.eclipse.sdkbundle_1.7.5/appengine-java-sdk-1.7.5/bin/appcfg.sh rollback /Documents/workspace/server_side/war

I can't realize what's wrong. i don`t know if is the right appcfg, because there is appcfg.cmd and appcfg.sh, i'm using an imac(Unix enviro) so i use the appcfg.sh to made the rollback. i've tried in several different ways. and nothing good happen. maybe i'm missing something.
thanks!

What happens when you run /Applications/eclipse/plugins/com.google.appengine.eclipse.sdkbundle_1.7.5/appe‌​ngine-java-sdk-1.7.5/bin/appcfg.sh without any arguments?

Nothing, just says command not found. like this sudo: /Applications/eclipse/plugins/com.google.appengine.eclipse.sdkbundle_1.7.5/appen‌​gine-java-sdk-1.7.5/bin/appcfg.sh: command not found

I also encountered the same problem as the original poster of this question, but I still got a permission denied error when attempting to rollback, even after changing the permissions of the appcfg.sh file.

It turned out I also needed to chmod 755 run_java.sh (located in the same directory as appcfg.sh), and then I was able to rollback without problems.

I thought I would post this in case anyone encountered the same set of issues that I did.
